『一』What is blockchain technology? What exactly is blockchain? What is blockchain?
In a narrow sense, blockchain is a way to A chained data structure composed of data blocks that are sequentially connected, and a cryptographically guaranteed distributed ledger that cannot be tampered with or forged.
Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, and uses cryptography to ensure data transmission and access. It is a new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and operate data securely.
[Infrastructure]
Generally speaking, the blockchain system consists of data layer, network layer, consensus layer, incentive layer, contract layer and application layer composition. Among them, the data layer encapsulates the underlying data blocks and related basic data and algorithms such as data encryption and timestamps; the network layer includes distributed networking mechanisms, data dissemination mechanisms and data verification mechanisms; the consensus layer mainly encapsulates network nodes Various consensus algorithms; the incentive layer integrates economic factors into the blockchain technology system, mainly including the issuance mechanism and distribution mechanism of economic incentives; the contract layer mainly encapsulates various scripts, algorithms and smart contracts, and is the core of the blockchain The basis of programmable features; the application layer encapsulates various application scenarios and cases of the blockchain. In this model, the chain block structure based on timestamps, the consensus mechanism of distributed nodes, economic incentives based on consensus computing power, and flexible programmable smart contracts are the most representative innovations of blockchain technology.
Extended information:
[Blockchain core technology]
Blockchain mainly solves the trust and security issues of transactions, so it addresses this issue Four technological innovations:
1. Distributed ledger means that transaction accounting is completed by multiple nodes distributed in different places, and each node records a complete account, so they all Can participate in supervising the legality of transactions and can also jointly testify for them.
The uniqueness of blockchain's distributed storage is mainly reflected in two aspects: First, each node of the blockchain stores complete data according to the block chain structure. Traditional distributed storage generally stores The data is divided into multiple parts for storage according to certain rules. Second, the storage of each node in the blockchain is independent and of equal status, relying on the consensus mechanism to ensure storage consistency, while traditional distributed storage generally synchronizes data to other backup nodes through the central node.
No node can record ledger data independently, thus avoiding the possibility of a single bookkeeper being controlled or bribed to record false accounts. Also because there are enough accounting nodes, theoretically, unless all nodes are destroyed, the accounts will not be lost, thus ensuring the security of the accounting data.
2. Asymmetric encryption and authorization technology, the transaction information stored on the blockchain is public, butAccount identity information is highly encrypted and can only be accessed with the authorization of the data owner, thus ensuring data security and personal privacy.
3. The consensus mechanism is how all accounting nodes reach a consensus to determine the validity of a record. This is both a means of identification and a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and strike a balance between efficiency and security.
The consensus mechanism of the blockchain has the characteristics of "the minority obeys the majority" and "everyone is equal". "The minority obeys the majority" does not entirely refer to the number of nodes, but can also be the computing power and the number of shares. Or other characteristic quantities that the computer can compare. "Everyone is equal" means that when a node meets the conditions, all nodes have the right to give priority to the consensus result, which will be directly recognized by other nodes and may eventually become the final consensus result.
4. Smart contracts. Smart contracts are based on these trustworthy and non-tamperable data and can automatically execute some predefined rules and terms. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and trustworthy, it will be easy to automate claims settlement in some standardized insurance products.
In the daily business of insurance companies, although transactions are not as frequent as those in the banking and securities industries, the reliance on trusted data continues unabated. Therefore, the author believes that using blockchain technology from the perspective of data management can effectively help insurance companies improve their risk management capabilities. Specifically speaking, it is mainly divided into risk management of policyholders and risk supervision of insurance companies.
Blockchain-Network
『二』 What is the concept of blockchain
Concept: Blockchain is a distributed data storage, New application models of computer technologies such as point-to-point transmission, consensus mechanisms, and encryption algorithms.
The essence of the blockchain is a distributed public ledger. Anyone can verify this ledger, but no single user can control it. Participants in a blockchain system jointly maintain a ledger: it can only be modified according to strict rules and consensus.
The development of blockchain has gone through three stages:
1. Incubation period: 2009-2012, the economic form was dominated by Bitcoin and its industrial ecology.
2. Embryonic period: The period is from 2012 to 2015. Blockchain entered the public eye with Bitcoin, new wallet payment and remittance companies appeared, and the blockchain economy spread to the financial field. The underlying technology of blockchain continues to innovate. Blockchain technology is divorced from the Bitcoin system.
3. Development period: In 2016, industry applications began to be explored, and a large number of blockchain startups emerged. The popularity of ICO in 2017 brought unprecedented attention to blockchain.
(2) Extended reading on the blockchain concept of national technology:
Three blockchain conceptsThree characteristics:
1. The core idea of the blockchain is decentralization: in the blockchain system, the rights and obligations between any nodes are equal, and all nodes have the ability to Use computing power to vote, thereby ensuring that the recognized result is the result recognized by more than half of the nodes. Even if it suffers a severe hacker attack, as long as the number of nodes controlled by the hacker does not exceed half of the total number of global nodes, the system will still be able to operate normally and the data will not be tampered with.
2. The biggest disruption of blockchain lies in the establishment of credit: in theory, blockchain technology can make WeChat Pay and Alipay no longer valuable. "The Economist" gave a vivid metaphor to the blockchain: simply put, it is "a machine that creates trust." Blockchain allows people to collaborate without trusting each other and without a neutral central authority. Combating counterfeit currency and financial fraud will no longer be needed in the future.
3. The collective maintenance of blockchain can reduce costs: In a centralized network system, the maintenance and operation of the system rely on the operation, maintenance and operation of platforms such as data centers, and costs cannot be omitted. Anyone can participate in the nodes of the blockchain. While participating in the recording, each node also verifies the correctness of the recording results of other nodes, which improves maintenance efficiency and reduces costs.
In one sentence, blockchain touches money, trust and power, which are the fundamental foundations on which human beings rely for survival.
『三』What is blockchain technology? What exactly is blockchain?
Blockchain technology is one of the top ten typical judicial technology applications on the Internet. Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms.
Blockchain is an important concept of Bitcoin. In fact, it is a decentralized database. Blockchain, as the underlying technology of Bitcoin, is a series of data blocks generated using cryptographic methods. Each data block contains a batch of Bitcoin network transaction information, which is used to verify the validity of its information (anti-counterfeiting) and generate the next data block.
Blockchain originated from Bitcoin. On November 1, 2008, a person who called himself Satoshi Nakamoto published the article "Bitcoin: A Peer-to-Peer Electronic Cash System", which elaborated on P2P network technology, encryption technology, timestamp technology, and block technology. The concept of electronic cash system framework such as chain technology marks the birth of Bitcoin.
(3) Extended reading on the blockchain concept of national technology:
The birth of blockchain:
The concept of blockchain was first proposed by Satoshi Nakamoto in 2008. In the following years, blockchain became the core component of the electronic currency Bitcoin: a public account for all transactions. By using peer-to-peer networks and distributed timestamp servers, blockchain databases can be autonomously managed.
The blockchain invented for Bitcoin makes it the first digital currency to solve the problem of repeated consumption. Bitcoin design has become a source of inspiration for other applications. On December 20, 2016, the Digital Currency Alliance-China FinTech Digital Currency Alliance and FinTech Research Institute were officially established.
『四』 What is blockchain? Decrypt the concept of blockchain
『五』 What technology is "blockchain"< /p> What kind of technology is "blockchain"?
Blockchain is an important concept of Bitcoin. It was released by Huobi in conjunction with the Internet Finance Laboratory of Tsinghua University PBC School of Finance and Sina Technology. The "2014-2016 Global Bitcoin Development Research Report" mentioned that blockchain is the underlying technology and infrastructure of Bitcoin. It is essentially a decentralized database and serves as the underlying technology of Bitcoin. Blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction and is used to verify the validity of the information (anti-counterfeiting) and generate the next block. .
In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-forgeable. Account book. Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, uses cryptography to ensure the security of data transmission and access, and utilizes automated Smart contracts are composed of scripts that program and compute data in a new decentralized infrastructure and normalize computing.
Domestic blockchain application platforms include an asset custody system based on blockchain technology jointly developed by the digital currency crowdfunding platform Biying China, China Post and IBM.
Blockchain is a decentralized, distributed ledger system participated by nodes. The data stored on it cannot be forged or tampered with, and is open to the public. Transparent, the information and value recorded by each account at any point in history can be found on the blockchain. The characteristics of the blockchain protocol provide the necessary foundation for the execution of smart contracts. The contract can be automatically executed and trusted according to established conditions without the need for audit by any centralized organization.
Blockchain technology is the underlying core of the Bitcoin system. Its essence is a decentralized ledger. When people conduct transactions through the Internet, a new transaction will be recorded on the ledger, and this ledger is A decentralized ledger is jointly maintained by everyone in the network. People can see ongoing transactions at the same time, and control is not in the hands of institutions or individuals. Transactions cannot be tampered with or forged, and they will be permanently stored in the ledger.
For example, the Tongxin Huzhu blockchain mutual aid platform has four major characteristics in applying blockchain technology:
Openness and transparency
PublicityTransparent, all information recorded on the blockchain is difficult to tamper with and cannot be hidden once recorded, and users can check it at any time.
Democratic decision-making
Bottom-up decision-making, the blockchain proposes a variety of different consensus mechanisms to help users effectively form bottom-up decisions and jointly participate in major decisions.
Accurate execution of rules
Accurate execution of rules. The smart contract technology defined on the blockchain converts all rules into public and clear codes, which can be executed accurately and accurately. Once anyone is identified Cannot intervene.
Never downtime
Never downtime, the blockchain based on the public chain is not affected by any organization or individual. As long as the incentive mechanism is effective and the Internet exists, the blockchain will exist.
What is blockchain? Blockchain is a decentralized shared accounting technology that allows all parties involved to establish a trust relationship at the technical level. Blockchain can be roughly divided into two levels: one is the underlying technology of the blockchain; the other is the upper-layer application of the blockchain, that is, the transformation, optimization or innovative application based on the blockchain. Blockchain is still in its infancy. Many people have discussed with me how we can ensure both rights and privacy at the same time. Of course, we are just exploring now. We need fair content across the entire network and clear protection. This is what I can only say. So far, this is my arrangement for the future.
Blockchain concept? The idea of blockchain is to be completely decentralized and rely on decentralized justice. In that case, theoretically the cost will drop a lot, proving that real assets and property rights can directly correspond to each other on the Internet. It has solved the problems of decentralization and asset ownership that were not solved by the first generation of Internet information. How big a role does big data play in financial innovation now? Only by registering big data can we know who it belongs to. In fact, this has always been a problem that we cannot solve now. This is not a small problem. If there is a technology in the capital market that makes the property rights of things that were originally unclear clear, that will be a big problem for us. The entire market is undergoing a huge transformation.
What is blockchain? Blockchain technology itself can solve data ownership, pricing and sharing mechanisms. This still cannot completely solve certain problems. To give a simple example when it comes to user privacy, I have a piece of data placed on the machine. The partner comes over and makes an insurance analysis to analyze the cooperation. There is a risk here for Or not, can we deal with it or clarify the property rights of the laboratory, and then clarify the processing rights and data rights. The common products produced by everyone are common to everyone. If we need to divide different things, how to price them and how to divide them? In addition to the technology of blockchain and a decentralized database, when it comes to the above mentioned tasks, it is another issue, and then there is the issue of pricing and the market mechanism. All fields have proven to recognize this rule, so this I think blockchain is a very good core technology, but it cannot cover all problems.question.
Introduction to Bubi Blockchain
Bubi Blockchain is mainly positioned to provide commercial-grade blockchain infrastructure services, which mainly includes building a blockchain system and building on top of the blockchain system. A support system with high expandability. On top of this support system are applications from all walks of life. Bubi focuses more on the underlying technology of the blockchain. In the past three years or so, a team of more than a dozen people has devoted almost all their energy to the research and development of the underlying technology. The reason why Bubi Blockchain chooses points has something to do with the market's promotion method. As we all know, blockchain is a technology that is very suitable for the issuance and trading of digital assets. Points are a digital asset that is naturally legal and compliant, and has a small impact because of its small amount. Therefore, it is a very suitable choice to use points as your first attempt at digital asset issuance. Issuing points based on the blockchain can indeed bring great help to the circulation and mutual exchange of points.
What is blockchain? The application of blockchain technology in the field of property transfer is only one aspect. In addition to reducing property transfer costs, blockchain technology can also be applied to various fields involving company stocks, financial derivatives, and points programs of commercial institutions. The blockchain community is currently focusing on promoting the wider application of this technology in the field of financial assets. Relatedly, various platforms that are still under development have also received very considerable investment.
Blockchain concept? Structurally or by definition, these things are very different. The U.S. dollar, or any currency, from a typical definition, is primarily used as a medium of exchange or store of value for economic activities. Within the geographical scope where a certain currency circulates, people in the region reach a consensus on the use of this currency, making it convenient for everyone to use the same currency to purchase goods or services (the function of currency as a medium of exchange). There is a responsibility to manage the currency through monetary policy in order to ensure the preservation of the value of the currency and avoid the occurrence of inflation (the store of value function of currency). In today's world, almost everyone uses some form of currency in their daily lives.
What is blockchain? Even developers within the blockchain community often easily overlook the big picture mentioned above. There are many competitive projects in the blockchain community, and they are also full of various disputes about the evolution direction of blockchain technology. Over time, some projects in the community will be successful, and others will not be so lucky. Things will not always develop in the direction we expect, but no matter how these projects in the early blockchain community develop, one thing is very clear, that is, blockchain technology has brought us at least A revolutionary function: Blockchain technology will greatly reduce the cost of financial property transfer, and blockchain will be used to control, manage and transmit financial property.
What is blockchain? Blockchain concept? After a certain application analysis, we return to the starting point. The definition of this blockchain technology will surely become more and more abundant with the expansion of applications, and people will discover more mysteries of blockchain technology.
Blockchain is an important concept of Bitcoin. It is essentially a decentralized database and serves as the underlying technology of Bitcoin. Blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction and is used to verify the validity of the information (anti-counterfeiting) and generate the next block. .
The blockchain is public on the Internet and can be queried in every offline Bitcoin wallet information. The functionality of a Bitcoin wallet relies on confirmation with the blockchain, and a valid check is called a confirmation. Usually a transaction requires several confirmations before it can proceed. The lightweight Bitcoin wallet uses online confirmation, which means it does not download the blockchain data to the device storage.
Many of Bitcoin’s altcoins also use the same design, but are slightly different in proof of work and algorithm. For example, using proof of stake and SCrypt, etc.
Blockchain timestamp service and proof of existence
This concept was proposed in Satoshi Nakamoto’s white paper [1], who created the first block, the “genesis block”.
On January 3, 2009, Satoshi Nakamoto, the founder of Bitcoin, left an unchangeable sentence in the genesis block:
“The Times 03/Jan/2009 Chancellor on brink of second lout for banks (on January 3, 2009, the chancellor was on the verge of implementing a second round of bank bailout)."
It was then that the British chancellor Darling was forced to consider a second bailout of the banks. In a time of crisis, this sentence was the headline of a front-page article in The Times that day.
With the blockchain’s timestamp service and proof of existence, the time when the first blockchain was created and the events that were happening at that time are permanently retained.
The Bitcoin company BTCC launched a service "Millennium Chain" in 2015, which is a blockchain engraving service, which uses the above principles. Users can engrave text on the blockchain through this service and store it permanently.
Bitcoin, Litecoin, Ruitai Coin, and Qianjin Card are all digital currencies based on blockchain technology.
Chongqing Jinwowo analyzed: Blockchain is actually a decentralized distributed ledger database.
How popular is blockchain technology?
Blockchain technology makes DAC possible. DAC is something that can fundamentally subvert the organizational model of human society. I believe that its impact on society will surpass the Industrial Revolution and become the most profound change that the Internet has brought to the world.
The essence of blockchain technology is decentralized data storage in a distributed structure.The method of storage, transmission and certification uses data blocks to replace the current Internet's reliance on central servers, so that all data changes or transaction projects are recorded on a cloud system, theoretically realizing data transmission. Self-certification of data.
Blockchain technology can be applied to many industries:
Art industry
Ascribe allows artists to use blockchain technology to declare ownership, Issue numberable, 100% editions of your work in digital form for any type of artwork. It even includes a marketplace where artists can buy and sell through their website without the need for any intermediary services.
Legal Industry
BitProof is the most advanced of the many document timestamp applications that have emerged in recent years, and will make traditional notarization methods a thing of the past. Compared with free versions including Blocksgin and OriginStaemp, BitProof provides more services, including one for intellectual property rights. Interestingly, BitProof recently collaborated with a San Francisco IT school to put all their students’ academic certificates on the blockchain, completely redefining how diplomas and student certificates are processed and used.
Development Industry
Colu is the first company to allow other companies to issue digital assets. They can "tokenize" various assets and have a profound impact on many people. Although the free Bitcoin wallet Counerparty also allows simple tokens to be issued and traded among other wallet holders, Colu tokens can be configured in various states and types, and can leave and return to the system. , and when storing data on the blockchain is too large, the data can be stored on the BitTorrent network.

『撒』 What is blockchain technology? What are the core components of blockchain technology?
What is blockchain technology? What are the core components of blockchain technology? What is blockchain technology:
Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system.
Blockchain is an important concept of Bitcoin. It is essentially a decentralized database and serves as the underlying technology of Bitcoin. The blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction and is used to verify the validity of its information (anti-counterfeiting) and generate the next block.
The core components of blockchain technology:
Blockchain mainly solves the trust and security issues of transactions, so it proposes four technological innovations to address this issue:
The first one is called distribution A type of ledger means that transaction accounting is completed by multiple nodes distributed in different places, and each node records a complete account, so they can all participate in supervising the legality of the transaction and can also jointly testify for it.
Different from traditional distributed storage, the uniqueness of blockchain distributed storage is mainly reflected in two aspects: First, each node of the blockchain stores complete data according to the block chain structure., Traditional distributed storage generally divides data into multiple parts for storage according to certain rules. Second, the storage of each node in the blockchain is independent and of equal status, relying on the consensus mechanism to ensure storage consistency, while traditional distributed storage generally synchronizes data to other backup nodes through the central node. [8]
No node can record ledger data independently, thus avoiding the possibility of a single bookkeeper being controlled or bribed to record false accounts. Also because there are enough accounting nodes, theoretically, unless all nodes are destroyed, the accounts will not be lost, thus ensuring the security of the accounting data.
The second one is called asymmetric encryption and authorization technology. The transaction information stored on the blockchain is public, but the account identity information is highly encrypted and can only be accessed with authorization from the data owner. This ensures data security and personal privacy.
The third one is called the consensus mechanism, which is how all accounting nodes reach a consensus to determine the validity of a record. This is both a means of identification and a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and strike a balance between efficiency and security.
The consensus mechanism of the blockchain has the characteristics of "the minority obeys the majority" and "everyone is equal". "The minority obeys the majority" does not entirely refer to the number of nodes, but can also be computing power, the number of shares, or other factors. A characteristic quantity that a computer can compare. "Everyone is equal" means that when a node meets the conditions, all nodes have the right to give priority to the consensus result, which will be directly recognized by other nodes and may eventually become the final consensus result. [8]
Taking Bitcoin as an example, it uses proof of work. Only when more than 51% of the accounting nodes in the entire network are controlled, it is possible to forge a non-existent record. When there are enough nodes joining the blockchain, this is basically impossible, thus eliminating the possibility of fraud.
The last technical feature is called smart contracts. Smart contracts are based on these trustworthy and non-tamperable data and can automatically execute some predefined rules and terms. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and trustworthy, it will be easy to automate claims settlement in some standardized insurance products.

Therefore, the author believes that using blockchain technology from the perspective of data management can effectively help insurance companies improve their risk management capabilities. Specifically speaking, it is mainly divided into risk management of policyholders and risk supervision of insurance companies.
Chongqing Jinwowo Analysis: The consensus mechanism is the core of blockchain technology. The consensus mechanism largely determines the degree of mutual trust between nodes in the entire blockchain system, and also determines other users’ views on the blockchain.The degree of trust in online data
What is the core component of blockchain technology? Analysis by Chongqing Jinwowo: Blockchain technology consists of three core technologies: consensus mechanism, common defense mechanism, and distributed storage.
The three core technologies are supported by machine trust, that is, through the support of network technology, breakthroughs in difficult problems such as point-to-point transactions, decentralization, non-tampering of recorded information, irreversible transactions, and information encryption are achieved through network technology support.
The development of blockchain technology is becoming more and more prosperous with the continuous expansion of applications. This powerful development force coming from the needs of various industries has caused rapid changes in blockchain technology, allowing various industries to achieve great results. The results are attracting more and more attention, and professional technologies and resources are constantly concentrated in this industry, thus bringing the development of blockchain technology into a new stage, and the impact of this development of blockchain technology has also much attention.
When talking about blockchain technology, Bitcoin has to be mentioned. Many people know that the electronic currency Bitcoin does not rely on the issuance of a specific monetary institution, but is generated through a large number of calculations by a specific algorithm. In fact, the core that truly supports Bitcoin is blockchain technology.
How does the invisible and intangible Bitcoin operate through blockchain technology? The interpretation circulated in the industry is that blockchain can be regarded as a technical solution for collectively maintaining reliable databases through "decentralization" and "trustlessness". In layman's terms, this technology can be understood as a technology in which everyone participates in accounting. In the past, people used centralized servers to keep accounts, but in the blockchain technology system, everyone can participate in accounting and jointly identify Authenticity of records.
"Through this technology, even if there is no neutral third-party organization, two parties that do not trust each other can achieve cooperation. In short, the blockchain is like a 'machine that creates trust.'" Bubi Company It is a leading blockchain service provider in China. It has made many breakthroughs in the blockchain technology platform, can meet scenarios with tens of millions of users, and has the ability to quickly build upper-layer application businesses.
The blockchain technology used by all parties involved in recording and storing information adopts a decentralized distributed structure, which saves a lot of intermediary costs and can better ensure data security; at the same time, it has a time stamp that cannot be tampered with. It can effectively solve problems such as data tracking and information anti-counterfeiting.
Will it become the next trend of Internet finance?
Although blockchain emerged with Bitcoin, the derived value of this technology has transcended digital currency. Bubi Blockchain focuses on the innovation of blockchain technology and products. It already possesses a number of core technologies and has developed its own blockchain service platform. With decentralized trust as the core, we are committed to building an open value circulation network to allow digital assets to flow freely. What Bubi wants to do is to create a new technology and product - to realize real value circulation and bring the Internet to a new level. With the application of this technology, you can transfer assetsThere is no central institution, and the direct transfer of assets between us can be achieved.
In the current international financial market, the U.S. Central Bank, Swiss Bank, and some insurance and futures companies are all competing to develop blockchain technology. Fang Liang introduced that in the Internet financial industry, blockchain technology will first affect financial infrastructure such as payment systems, securities settlement systems, and transaction databases; later, the technology will also expand to general financial services, such as credit systems and "anti-money laundering" "wait.
"The payment and clearing system in the financial field will evolve towards decentralization. The electronic ledger supported by blockchain technology is a reliable system that is error-free and cannot be tampered with. It has various functions for payment, clearing, transaction, confirmation of rights, etc. A profound impact," Li Yan said.
Therefore, industry insiders believe that blockchain technology may be the next trend in the Internet financial industry. As the interconnection of all things deepens, Yang Tao, assistant director of the Institute of Finance, Chinese Academy of Social Sciences, also said that blockchain will make it possible for all individuals to become important nodes in the allocation of financial resources, and will also promote the improvement of existing financial system rules. Build a shared and win-win financial development ecosystem.
Blockchain technology will affect many industries
"Blockchain technology has been widely used in the era of big data." Li Yan said frankly that in addition to the Internet financial field, blockchain technology has been used in many industries. It has been applied in many fields and has shown great prospects.
For example, the healthcare industry has benefited greatly from blockchain technology. In reality, patient private information leaks often occur, and centralized database or file cabinet management in medical departments is no longer the optimal choice. Medical institutions are using blockchain technology to keep patients' private information confidential.
In addition, blockchain technology also has important legal implications. In some civil fields, it is often necessary to provide evidence to determine blame, and blockchain technology can record every step and help judicial authorities identify the specific responsible person.
"Especially in the field of assets, whether it is physical assets such as real estate and cars, or intangible assets such as health and reputation, this technology can be used to complete registration, transactions, and tracking. It can be said that any production and life that lacks trust In all fields, blockchain technology will have its place."
The development of blockchain technology has also brought about changes in the operational concepts of various industries. New technologies and new concepts have promoted new developments in various industries. This The impact of this driving force on society and the promotion of economic activities are also huge. Many new industry phenomena will occur one after another, and the public is also waiting and watching, expecting this brand-new technology to be used by various industries and better benefit all industries.
The so-called blockchain technology, also known as distributed ledger technology, is an Internet database technology that is characterized by decentralization. , open and transparent, allowing everyone to participate in database records.
Explained in layman’s terms: If the database is assumed to be a ledger, readWriting a database can be regarded as an act of accounting. The principle of blockchain technology is to find the person with the fastest and best accounting within a period of time. This person will do the accounting, and then the information on this page of the ledger will be Sent to everyone else in the entire system. This is equivalent to changing all the records in the database and sending them to every other node in the entire network, so blockchain technology is also called a distributed ledger.
What is the core technology of Jinwowo blockchain technology?
Chongqing Jinwowo analyzes the core technologies of blockchain technology as follows:
Distributed ledger technology, asymmetric encryption technology and smart contracts.
The core of the blockchain is that it stores all information in an independent personal computer network, making it a decentralized and distributed structure.
This means that the system is not owned by a controlling company or person, but that everyone can use and run the system.

What is blockchain technology?Blockchain has been hyped up like crazy, but you know nothing about it!
Blockchain is a distributed database system participated by different nodes and an open ledger system.
It consists of a series of data blocks or data packets generated according to cryptographic methods, that is, blocks. Each block of data information is automatically timestamped, thus Calculate a data encryption value, that is, a hash value (hash).
Blockchain technology is essentially a distributed accounting technology. It allows everyone to have an instantly synchronized account book in their hands. Every transaction that occurs in the entire network will have thousands of backups and synchronous records. When perpetrators attempt to tamper with ledger data, they must change the ledger in the hands of the majority of people to achieve their goal.
『8』BMEX: The beginning of the long-term prosperity of the blockchain industry has arrived. What is blockchain technology?
1. The concept of blockchain technology
< p>Blockchain technology is a new technology that has gradually emerged with the rise of encrypted digital currency. It adopts a distributed computing model, uses blockchain to store data, and uses cryptographic principles to ensure the security of transmission and access. Data storage is Internet users jointly maintain and supervise, and have significant characteristics such as decentralization, transparency and openness, and data cannot be modified[2], which uses distributed storage and computing power to make the rights and obligations of the entire network nodes the same. The essence of the data in the system is jointly maintained by the entire network nodes, so that the blockchain no longer relies on the central processing node to achieve distributed storage of data. Recording and updating, so its application is not limited to currency as an asset type. Currently, application research in various industries is relatively extensive.
